CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 63/297,379 filed Jan. 7, 2022, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND

Exemplary embodiments of the present disclosure relate to the art of air conditioning systems, and more particularly, to a condensate drain assembly for a heat exchanger of an air conditioning system.

In a conventional refrigerant cycle, a compressor compresses a refrigerant and delivers the compressed refrigerant to a downstream condenser. From the condenser, the refrigerant passes through an expansion device, and subsequently, to an evaporator. The refrigerant from the evaporator is returned to the compressor. In a split system heating and/or cooling system, the condenser may be known as an outdoor heat exchanger and the evaporator as an indoor heat exchanger, when the system operates in a cooling mode. In a heating mode, their functions are reversed.

In the split system, the evaporator is typically a part of an evaporator assembly coupled with a furnace. However, some cooling systems are capable of operating independent of a furnace. A typical evaporator assembly includes an evaporator coil (e.g., a coil shaped like a “V”, which is referred to as an “V-frame coil”) and a condensate pan disposed within a casing. A V-frame coil is typically referred to as a “multi-poise” coil because it may be oriented either horizontally or vertically in the casing of the evaporator assembly. During a cooling mode operation, a furnace blower circulates air into the casing of the evaporator coil assembly, where the air cools as it passes over the evaporator coil. The blower then circulates the air to a space to be cooled.

Refrigerant is enclosed in piping that is used to form the evaporator coil. If the temperature of the evaporator coil surface is lower than the dew point of air passing over it, the evaporator coil removes moisture from the air. Specifically, as air passes over the evaporator coil, water vapor condenses on the evaporator coil. The condensate pan of the evaporator assembly collects the condensed water as it drips off of the evaporator coil. The collected condensation then typically drains out of the condensate pan through a drain hole in the condensate pan.

DETAILED DESCRIPTION

A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.

With reference now to the FIGS., an exemplary condensate drain assembly 20 for use with a multi-poise heat exchanger coil 10 is illustrated in more detail. In an embodiment, the condensate drain assembly 20 includes a first drain pan 22 and a second drain pan 24 arranged at an angle relative to the first drain pan 22. In the illustrated, non-limiting embodiment, the second drain pan 24 is orthogonal to the first drain pan 22. However, embodiments where the second drain pan 24 is arranged at another angle relative to the first drain pan 22 are also contemplated herein. When the multi-poise heat exchanger coil 10 is in a first, vertical configuration (FIG. 1 ), the first drain pan 22 has a generally horizontal orientation and the second drain pan 24 has a substantially vertical orientation. Further, when the multi-poise heat exchanger coil 10 is in the second, horizontal configuration (see FIGS. 2 and 3 ), the first drain pan 22 has a generally vertical orientation and the second drain pan 24 has a substantially horizontal orientation.

With reference now to FIGS. 4-9 , an exemplary first drain pan 22 is illustrated in more detail. As shown, the first drain pan 22 includes a drain pan panel 30, a front wall 32, a rear wall 34, and opposing first and second sidewalls 36, 38. The rear wall 34 and opposing sidewalls 36, 38 extend from the sides of the drain pan panel 30 to define a hollow interior 40 operable to collect condensate therein. When the first drain pan 22 has a generally horizontal orientation, the portion of the drain pan panel 30 located adjacent to the rear wall 34 may be vertically elevated relative to the portion of the drain pan panel 30 arranged adjacent to the front wall 32, such that condensate within the hollow interior 40 is configured to drain towards the front wall 32. Alternatively, or in addition, a width of the drain pan panel 30 may decrease from a first width adjacent to the rear wall 34 to a second, smaller width adjacent to the front wall 32. It should be appreciated that the first drain pan 22 may be constructed from any suitable material for collecting condensate, including, but not limited to plastic, for example.

In the illustrated, non-limiting embodiment, a portion of the heat exchanger coil 10, such as an apex 12 thereof for example, is receivable within the hollow interior 40 of the first drain pan 22 (see FIG. 9 ). Accordingly, in an embodiment, each of the first sidewall and the second sidewall 36, 38 may extend from the drain pan panel 30 at any angle complementary to the contour of the portion of the heat exchanger coil 10 receivable therein. For example, as shown, the opposing sidewalls 36, 38 may extend from opposite sides of the drain pan panel 30 at equal and opposite angles. Further, in an embodiment, one or more ribs 42 protrude from one or both sidewalls 36, 38 towards the hollow interior 40. The plurality of ribs 42 are configured to align or position the portion of the heat exchanger coil 10 within the hollow interior 40, regardless of the orientation of the first drain pan 22.

In an embodiment, the front wall 32 includes a flange 44 extending radially outwardly beyond the opposing sidewalls 36, 38. Further, the front wall 32 may have an opening 46 (see FIGS. 5 and 8 ) formed therein such that fluid within the hollow interior 40 is configured to flow through the opening 46 in the front wall 32. As shown, a distribution channel 48 may be connected to the hollow interior 40 of the of the first drain pan 22 via the opening 46 in the front wall 32. The distribution channel 48 includes a bottom 49 (see FIG. 13 ), a channel wall 50 offset from the front wall 32, and two connecting walls 52, 54 coupled to the bottom and extending between the channel wall 50 and the front wall 32. A partially enclosed drain channel 56 is defined between the front wall 32, the channel wall 50, the connecting walls 52, 54, and the bottom. Accordingly, within the first drain pan 22, condensate is configured to flow from the drain pan panel 30 into the drain channel 56.

One or more apertures may be formed in a portion of the distribution channel 48, such as in the channel wall 50 for example. In an embodiment, the channel wall 50 includes at least one drain 57 having a first aperture 58 configured to function as a primary drain and a second aperture 60, arranged directly adjacent to the first aperture, configured to function as a secondary drain. Although the channel wall 50 is illustrated as having a first drain 57 adjacent a first end, near connecting wall 52 and a second drain 57 adjacent a second, opposite end thereof, near connecting wall 54 embodiments having only a single drain 57 arranged at any location are also contemplated herein.

In an embodiment, the distal or free ends 62 of at least one of the opposing sidewalls 36, 38 is bent such that when the first drain pan 22 is in the second, vertical configuration (FIG. 8 ), a channel is formed at the distal ends of the sidewalk 36, 38. These channels formed in the sidewalls 36, 38 are fluidly connected with the drain channel 56 such that condensate collected within the channel of the sidewall 36, 38 flows into the drain channel 56. Although the free end of both opposing sidewalls 36. 38 are bent to form a channel in the illustrated, non-limiting embodiment, embodiments where the distal end 62 of only the sidewall 38 arranged vertically below the apex 12 of the heat exchanger coil 10 is bent are also contemplated herein.

With reference now to FIGS. 8 and 10-13 , an exemplary second drain pan 24 is illustrated in more detail. As shown, the second drain pan 24 includes a base 70 and a plurality of walls extending at an angle from the sides of the base 70 to define a hollow interior 72 configured to collect condensate therein when the heat exchanger coil 10 is in the second, horizontal configuration. The plurality of walls include a front wall 74, a rear wall 76, and two opposing sidewalls 78, 80. In the illustrated, non-limiting embodiment, one of the walls, such as the front wall 74, for example, includes a drain 82. The construction of the drain 82 may be similar or different than the drain 57 of the first drain pan 22. In an embodiment, the drain 82 has a first aperture 84 configured to function as a primary drain and a second aperture 86 configured to function as a secondary drain.

In an embodiment, a crease 88 is formed in the base 70 of the second drain pan 24 and extends generally between the front wall 74 and the rear wall 76. One or more of the multiple portions of the base 70 defined by the crease 88 may have a sloped configuration configured to direct water within the hollow interior 72 towards the drain 82.

Arranged generally adjacent to one of the sidewalls of the second drain pan 24, such as sidewall 80, for example, may be at least one header protrusion or rib 90. The header protrusion 90 may be used to properly position a first header (not shown) of the heat exchanger coil 10 relative to the second drain pan 24. In the illustrated, non-limiting embodiment, the header protrusions 90 are arranged in pairs that cooperate to form a contour complementary to the portion of the first header receivable therein. A wall 92 may extend generally perpendicular to the base 70 at a location directly adjacent to the plurality of header protrusions 90. In an embodiment, the height of the wall 92 varies between the front wall 74 and the rear wall 76 based on the slope of the adjacent portion of the base 70 such that a top surface of the wall 92 is arranged within a horizontal plane. The wall 92 may form a barrier to prevent (or at least mitigate) any condensate collected within the hollow interior 72 from being blown therefrom.

With reference to FIGS. 12-13 , in an embodiment, a stepped feature or recess 94 is formed in the second drain pan 24, such as at the interface between the front wall 74 and the sidewall 78. A width of the stepped feature 94 may be sized to receive a portion of the distribution channel 48 of the first drain pan 22 therein. As best shown in FIGS., the end of the distribution channel, such as connecting wall 54, for example, is positioned within the stepped feature 94 such that a flange 55 associated therewith is arranged in contact or overlapping arrangement with the portion of the base 70 adjacent to stepped feature 94. Accordingly, when the first drain pan 22 is mounted in such a configuration, water within the drain channel 56 is configured to flow into the hollow interior 72 of the second drain pan 24, toward the drain 82.

A second manifold or header (not shown) of the heat exchanger coil 10 may be separated from the first header by a distance and is mounted generally within a gutter 96. In an embodiment, the gutter 96 is fluidly connected to the second drain pan 24 by one or more cross-channels 100, illustrated in FIGS. 14-20 . Although two cross-channels 100 are shown, it should be understood that a condensate drain assembly 20 including only a single cross-channel 100, or alternatively, more than two cross-channels 100 are within the scope of the disclosure. The first end 102 of a cross-channel 100 may have a contour complementary to a portion of the first header and a second end 104 of a cross-channel 100 may have a contour complementary to a portion of the second header.

In the illustrated, non-limiting embodiment, the at least one cross-channel 100 includes a body extending between the first end 102 and the second end 104 having a U or C-shape defined by a rear wall 106 and two opposing sidewalls 108, 110. The front side of the cross-channel 100 may be generally open, as best shown in FIG. 16 , or alternatively, may be closed. Although a plurality of support pieces 112 are shown as extending between the sidewalls 108, 110 at intervals over the length of the cross-channel 100, such as to increase the strength and rigidity of the cross-channel 100, for example, embodiments where the cross-channel 100 does not have any support pieces 112 are also contemplated herein.

With reference now to FIGS. 16 and 17 , a recess 114 may be formed at the first end 102 of the cross-channel 100. In an embodiment, the recess 114 is sized and shaped to receive a header protrusion 90 therein. Accordingly, when installing the cross-channel 100 relative to the second drain pan 24, the cross-channel 100 may be generally aligned with a respective header protrusion 90 such that the header protrusion 90 is positioned within the recess 114. Alternatively, or in addition, a portion of the cross-channel 100, such as near the first end 102 for example, may be receivable within a groove 116 formed in the sidewall 80 of the second drain pan 24, such as near a header protrusion 90, for example.

A slot 118 may be formed in the back wall 106 of the cross-channel 100 near the second end 104. In an embodiment, a portion of the gutter 96 is receivable within the slot 118 to couple the gutter 96 to the cross-channel 100. This connection may not only structurally connect the gutter 96 and the cross-channel 100, but may also fluidly couple the gutter 96 to a flow path defined between the first and second ends 102, 104 through the interior 119 of the cross-channel 100. As a result, any water or condensate that originates near the second manifold of the heat exchanger coil 10 when in the second configuration, may be configured to flow to the drain 82 of the second drain pan 24 via the one or more cross-channels 100.

In an embodiment, the condensate drain assembly 20 additionally includes an upper channel 120. The upper channel 120 may be locally arranged in overlapping arrangement with the gutter and second manifold, as shown in FIG. 4 . In another embodiment, the upper channel 120 may extend over a full width of the heat exchanger coil 10 (see FIG. 3 ) such that the upper channel couples 120 to an end of the first drain pan 22, such as to an end 52 of the distribution channel 48, for example. The upper channel 120 includes an internal chamber (not shown) for holding water or other condensate therein.

The upper channel 120 may be connected to one or both of the gutter 96 and the cross-channels 100 by one or more mounting brackets 122. The mounting bracket 122 may similarly have a contour complementary to an adjacent portion of the second header 16 receivable therein. In an embodiment, the at least one mounting bracket 122 has a fluid channel (not shown) formed therein that fluidly couples the internal chamber of the upper channel 120 with the gutter 96 and/or directly with the interior of the cross-channel 100. Accordingly, when the heat exchanger coil 10 and the condensate drain assembly 20 are in the second, horizontal configuration, a fluid flow path extends from the upper channel 120, through the mounting bracket 122 and cross-channel 100 to the second drain pan 24.

A condensate drain assembly 20 as illustrated and described herein is suitable to drain water from either a vertically oriented heat exchanger 10 or a horizontally oriented heat exchanger 10.
